Thanks for this reminder! I had bought replacements from America Tires many years ago, and benefited from that program. I just looked at their www and it seems one has to get the cert within 30 days of buying a tire? I took delivery of my GGT in January, so that won't work for me until I burn through the stock skids.You’re right, but… you’ll hear plenty of arguments both directions, but EV tires with sound-insulating foam are generally not repairable. Some shops are happy to cut out a piece of foam, plug it, and do it, but the manufacturers do not recommend it. As I have the discount tire/americas tire certs on my car, I would just drive it to the nearest one, get my new tire, and pay $100 to certify that new tire.
I highly recommend getting the DT/AT certs. You do not have to have bought the tires from them. I’ve never used it, but I’m glad I have it.
BTW it was the Volvo / Polestar dealer that told me the stock P-Zero would have been repairable -- if I'd not used the repair goo that came with the car's included 12v compressor / repair kit.
Of course we trust them...
